As an additional security measure, the Catalyst Cloud APIs only accept requests
from whitelisted IP addresses. If you have provided an IP address during sign
up, you should be able to reach the APIs from that IP. Otherwise, you can open
a support request via the
dashboard at any time to request a change to the white-listed IPs.

All compute instances on the Catalyst Cloud have whitelisted IP addresses by
default. Because compute instances are whitelisted, you can use them as a
“jumpbox” by creating an instance using the cloud dashboard, SSH-ing into the instance, and installing and configuring the CLI tools
there. An explanation of launching an instance using the web dashboard can be
found here.

The compute instances you launch on the Catalyst Cloud are created in your
private network by default. You have the option to associate a floating IP
(public IP) with your compute instances to expose them to the Internet. You can
use security groups (similar to firewalls) to define who has access to your
compute instances, as explained in Security groups.
